CTNS, or Cerebral Toxoplasmosis, is a neurological condition caused by the Toxoplasma gondii parasite. This parasite is commonly found in cat feces and can infect humans, particularly those with weakened immune systems, such as individuals with HIV/AIDS. CTNS can lead to symptoms like headaches, confusion, and seizures, and it often requires medical treatment with antiparasitic medications. Diagnosis of CTNS typically involves imaging studies, such as MRI or CT scans, to identify lesions in the brain. Blood tests may also be conducted to detect antibodies against the Toxoplasma gondii parasite. Early diagnosis and treatment are crucial for improving outcomes and preventing complications.
